Shock-Absorbing Server Rack Pallets for Vibration Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pallets for transporting server racks are prone to tipping, turning, and shaking due to external forces, leading to potential physical damage from vibrations and shocks during transportation.
Innovation Solution
A shock-absorbing pallet design featuring a top cover, bottom cover, isolation devices with shock-absorbing components, and supporting layers, which are secured between the covers to absorb vibrations and distribute forces uniformly, allowing relative movement between the pallet and the server rack to dampen external forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid pallet is used to support server racks, then the pallet provides structural stability and support, but it transmits external forces and vibrations directly to the racks, causing potential physical damage
Solution Approach 1:
The patent introduces isolation devices as intermediary elements between the rigid pallet structure and the server racks. These isolation devices include shock-absorbing components that act as mediators to decouple the direct transmission path of vibrations and shocks from the racks, while still providing necessary structural support through the rigid pallet framework.
Solution Approach 2:
The patent employs composite construction by combining rigid structural elements (pallet framework, top cover, bottom cover) with shock-absorbing materials (isolation devices, supporting layers). This composite approach allows the system to simultaneously maintain structural integrity and provide vibration damping, resolving the contradiction between strength and harmful factor transmission.
2Object-affected harmful factors
If isolation devices are added to absorb shocks, then vibration and shock transmission is reduced, but the device complexity and structural complexity increase
Solution Approach 1:
The patent divides the shock absorption function into multiple discrete isolation devices positioned at different locations on the pallet. Each isolation device is a separate, modular component that can be independently designed and positioned. This segmentation allows the complex shock absorption function to be distributed across multiple simple, standardized units rather than requiring a single complex system.
Solution Approach 2:
The isolation devices incorporate dynamic shock-absorbing components that can deform and move in response to external forces. This dynamic behavior allows the structure to adapt to varying vibration and shock conditions without requiring complex active control systems or multiple different types of isolation devices for different scenarios.
3Reliability
If the pallet structure is made more complex with isolation devices and supporting layers, then shock absorption capability is improved, but manufacturing complexity and assembly difficulty increase
Solution Approach 1:
The patent segments the shock absorption system into discrete, pre-fabricated components (isolation devices, supporting layers) that can be manufactured separately and then assembled onto the pallet. This segmentation enables each component to be optimized for its specific function during manufacturing while simplifying the overall assembly process, as components can be attached in a systematic sequence rather than requiring complex integrated fabrication.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The shock-absorbing pallet effectively reduces the impact of external forces on server racks during transportation, minimizing the risk of physical damage and ensuring safer handling and delivery of information-handling systems.
Implementation Method 1
a suspension spring disposed around the cylindrical body between the first stopper panel and the second stopper panel, wherein a displacement of the suspension piston causes the suspension spring to compress between the first stopper panel and the second stopper panel
Implementation Method 2
configured to move relative to the server rack to dampen vibration during transportation of the server rack
